history

A Brief History of Kefir

biology

Tibicos are found around the world, with no two cultures being exactly the same. Typical tibicos have a mix of Lactobacillus, Streptococcus, Pediococcus and Leuconostoc bacteria with yeasts from Saccharomyces, Candida, Kloeckera and possibly others. Lactobacillus brevis has been identified as the species responsible for the production of the polysaccharide (dextran) that forms the grains.[1]

Interesting but possibly not confirmed:

Supposedly the tibicos grains are consisting of two layers, outer in which the bacteria and yeast are embedded (or attached to) and inner “sponge” like in which the carbon dioxide is accumulated (citation needed).
